Tabular Corundum
Application:
Tabular Alumina can be used as the main component in aluminium-carbon, aluminium-magnesium-carbon, magnesia-aluminium-carbon, magnesia-spinel and aluminium-chromium refractory bricks. It can also be introduced into high aluminium amorphous refractories as the enriched alumina component. It can be widely used in steel, casting, ceramics and other industries, and its application in iron and steel industry almost covers. The whole process of ironmaking and steelmaking has been completed.Other applications include electrical insulators, kiln furniture and catalyst carriers. Finely ground plate corundum powder is an excellent filler for epoxy or resin systems to achieve the desired high insulation strength, thermal conductivity and wear resistance.
Properties:
As a kind of pure sintered corundum material, plate corundum has extremely high heat resistance, mechanical strength and abrasion resistance, high chemical purity, excellent insulation properties and good acid and alkali corrosion resistance.
